Windows 10 users have reported one unusual problem after the update from Windows 8/8.1 to Windows 10. According to the users, after the update and reboot users were left with a black screen. Main cause of this problem are Master Boot Record issues, and you can easily fix them is you have Windows 10 Recovery disk. If you don’t have Windows 10 Recovery disk you can use your bootable install media for Windows 10 or you can find a working Windows 8.1 device and create recovery disk.
In order to create a recovery disk from a working Windows 10 device you’ll need to do the following:
- On the working device, open the Charms and select Search.
- In the Search charm type ‘Create a Recovery Drive’.
- You’ll get a prompt asking you to allow the Recovery Media Creator Wizard to run so make sure that you allow it. Insert a writable USB Key, however, bear in mind that all of your files on this USB key will be deleted.
- After that in the Recovery Media Wizard you need to select your USB key as your Recovery drive.
- The Recovery Drive Creator will format the USB key and create a bootable partition with the Recovery tools installed. One the process is finished, restart your computer and boot your PC via the new USB Recovery Drive.
- You might have to hit ESC or F9 during the reboot to select your boot drive. After pressing ESC or F9, you just need to selected the USB key you created during the Recovery Drive Creator.
- From the Recovery Disk Menu – select Troubleshoot.
- From the Troubleshoot menu – select Advanced options.
- From the Advanced options menu select – Command Prompt.
- After that in the command prompt type ‘bootrec /fixmbr’ and press Enter. You should see a confirmation like above, so type exit and hit Enter to exit.
After doing there you’ll have two options at your screen…you can continue to Windows 8.1 or Turn off your PC and restart it, which we highly advise.
